Genuine E3D V6 All-Metal HotEnd 1.75mm Universal w/ Bowden Full Kit 12V (V6-175-B)

Not sure why some have reported this to be a clone. The company is listed on the E3D site as a legitimate reseller, so I don't see why they wouldn't sell the genuine article. Mine certainly appears to be genuine, coming with a cartridge thermistor and beautifully machined. It prints very well on my CR-10S (so far printed PLA and PETG), and using dpetsel's wonderful Petsfang V2 mount from Thingiverse, went together super smoothly. Good experience overall... fast shipping and no missing parts.

Yeap, I received mine relatively quickly. Received in a tiny box, not the one I see as "original" from the e3d website, but everything was in there... If it is not original then it is an extremely perfect copy ;) Assembly takes one to two hours if you are meticulous as me and reads all the instructions from the wiki link found in e3d site and a couple of videos of what to do and what not to do. The hard part is to introduce the thermistor with the fiberglass isolators inside the metal block.. The very first print with the new hotend installed was pretty good. The only problem found is that the fan sends the airflow directly to the bed and if you are printing with ABS for sure it will increase the warping/corners lift. So I printed the fan duct ( 547325 thingiverse part created by Tec2C ) and fixed the airflow issue. Bottom line is I'm very happy with this hotend, pretty much better than the mk8 tha came with my Prusa I3. Faster prints with better precision. I recommend you to purchase a 0.3mm nozzle for a better resolution/ fine details print. It is available directly in the e3d site and the shipping is incredibly fast to US (FedEx). Be careful don't break the thermistor.

I was hesitant to purchase this via Amazon given the large number of fakes and knockoffs and even reviewing showing they had received them on this listing. However mine arrived via 3DMakerWorld which is a verified E3D reseller in the US per the E3D website. Mine came with every little piece it was supposed to, as well as extras. Everything packaged identically as one would get from E3D, just minus the little Haribo candy. Had no problems assembling or mounting this on my Primary MK2s other then I needed to source a 40w Hear cartridge elsewhere, as this only has a 30w. Not the sellers fault at all, as I had planned for this. Hotend prints like a dream, no a single issue this far and very pleased with my purchase.

After installation and during testing/calibration: with about 4 hours of non-continuous printing complete, extruder temp started "jumping" by 7-10 degrees up AND down during a print, and printer shut down. After restart, problem continued, then seemed to stop... then PLA filament jammed. After disassembling and clearing the jam, heatbreak could NOT be reinserted into the heatsink, and I noticed stripped threads on the heatbreak which I'm certain I didn't do. Waste of time/money.

This is a beautifully made piece of equipment. It's practically a work of art. Excellent assembly instructions. I'm new to 3D printing; I built a Rostock "delta" printer using mostly scavenged parts, and was struggling to print using a J-head hot-end, with the little tiny glass thermistor taped in place with Kapton tape. I thought I had something terribly wrong because of the awful print quality I was getting. I read about this hot-end and decided to give it a try. It works _great_. I've even crashed it into the print surface a few times, as well as having the printer drag it across the plywood printer base, and it's still working wonderfully. Well designed, precisely made, and worth every penny!

As far as I know, E3D etches their logo onto the heater block. The included aluminum block with the 30W heater cartridge and thermistor, have a hard time to heat to 200C without triggering an error in firmware. One could probably tweak firmware settings to circumvent this behavior, but I probably would make it worse. So, I am not sure if this product is 100% genuine or if there is a mix up with E3D part and something from china? Some of the included components seem genuine, some don't. I can PID tune to about 195C, beyond the firmware says I am not happy. My best guess, the 30W cartridge can't heat fast enough to be reliable with Marlin Firmware. Addition: After running several PID tuning cycles, the setup seemed to work even with PETG until today, that is. Apparently the thermistor reported way low temperatures and killed my print, 2 hrs in. It seems to me, that the individual components in my batch, don't work in harmony. The 30 Watt should be able to get up to 300C, it might just take a little longer, but the thermistor simply reporting 227C whilst the requested temperature is 235C is not what I call reliable (after PID tune). The china made thermistor I have in the box (5 at the cost of 1 E3D) work far better. I will toss the E3D thermistor and heater cartridge with low cost ones and probably be happy.

Pros: Looks good. Lays down a nice consistent line of plastic. Kit was fairly easy to assemble. Even without soldering. Plenty of online assembly documentation. Lots of nozzle options. Cons: The fan: No matter which way you mount it to the fan shroud, air blows on to the plastic you just printed (If you have it wired for always on like I do). I haven't really tried printing without the fan though so I'm not sure whether this has a huge impact on print quality or not. Not a huge difference in print quality in comparison to my old print head (Ubis hot end for the Printrbot). If you are just an enthusiast who plans on printing PLA or ABS, stick with your standard print head unless you find yourself wanting to print more hardcore filaments or your print head breaks or if you want a bigger bead of plastic for stronger prints like I did! No real easy way to 'Securely' mount it in to my printer seeing as I need an adapter that takes up almost the entire hot end mount, leaving about 1/8" to actually mount the E3D Hot end to the extruder assembly. If you have a Printrbot and want one of these consider this: I have had the print head actually fall out of its mount during a print because it wasn't stuffed up far enough! Oops! (Not E3Ds problem, Kept out of my rating. More FYI) Mounting the thermistor was a little bit of a pain. The documentation makes it look easy, but getting it to where the thermistor doesn't come unseated while bending its wires to screw them into place was a little painful. Maybe I am special though? When it heats up, it leaks PLA. Annoying! Again I am not sure if this is an end user problem or a problem with the print head. With my old print head, the ubis, I printed PLA effectively at 185c. I now have to crank up the heat to 210c to get a consistent bead, which is way too hot in my opinion. Im not sure if this is because my awesome thermistor mount job isn't reading the temp correctly or if this is the print head's 'personality'. I am not the only one who prints PLA at 210c though so it could be either. I needed to reflash my printers firmware, which I am not sure I did correctly, or even did at all! Some better instructions on this would be nice! (Not E3Ds problem, Kept out of my rating. More FYI) Other thoughts: It was smaller than I expected. If you're looking to do a dual print head with these, it would be pretty easy to design a custom mount for them! Not sure if the extra 10 bucks for the bowden add on was worth it. I actually ordered it with the bowden add on because the direct print head was going to take an additional 3 weeks to get to my house. Ain't nobody got time for dat!

Give yourself a great new toy, this thing upped my game just as I'd hoped! Layer lines are a good deal more uniform and clean, this is my first day using it (on a cheap Anycubic Delta) and I look forward to every new print from here on out -- as well as the chance to begin working with Nylon and some of the other interesting higher-temp thermoplastics. On a somewhat related note ... another experiment done today has taken me quite by surprise, the flying extruder. Just a bunch of rubber-bands suspending things from the top end of the Delta rods for now, but My Oh My! I felt compelled to mention is here merely because after a good amount of online browser study the improvements in extrusion response and overall print quality brought about by this configuration seem not to have been stressed enough.

Don't know whether it's original or not .....as no original packing was there with it....So still don't that I have nailed it or I have been nailed...
